/**
 * 使用RabbitMQ
 * 1、引入amqp场景：RabbitAutoConfiguration   就会自动生效
 *
 * 2、给容器中自动配置了
 *      RabbitTemplate、AmqpAdmin、CachingConnectionFactory、RabbitMessagingTempla；
 *      所有的属性都是 spring.rabbitmq
 *      @ConfigurationProperties(prefix = "spring.rabbitmq")
 *      public class RabbitProperties
 * 3、给配置文件中配置   spring.rabbitmq 信息
 * 4、@EnableRabbit：@EnableXxxxx；开启功能
 * 5、监听消息：使用@RabbitListener；必须有@EnableRabbit
 *      @RabbitListener：类+方法上（监听哪些队列即可）
 *      @RabbitHandler：标在方法上（重载区分不同的消息）
